[0001] This utility model belongs to the technical field of display screen manufacturing, specifically relating to a light-emitting pre-pressure head and pre-pressure device. Background Technology

[0002] A display screen is an electronic display device, with common types including LCD screens and LED screens. FOG screens, in particular, require a CCD lens for alignment to secure the FPC board to a predetermined position on the screen.

[0003] In the process of developing this utility model, the inventors discovered at least the following problems in the prior art.

[0004] Misalignment can easily occur when bonding FPC boards and displays, affecting bonding accuracy. Utility Model Content

[0005] One of the objectives of this invention is to provide a light-emitting pre-pressure head that addresses the shortcomings of existing technologies. By optimizing the structure of the pre-pressure head, the problem of misalignment during the bonding of FPC boards and displays can be solved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A light-emitting preload head includes a mounting base with a mounting groove at the bottom; an LED light disposed in the mounting groove; and a quartz strip embedded in the mounting groove; wherein the bottom of the quartz strip has a protrusion that at least partially protrudes from the plane of the bottom of the mounting base.

[0008] Preferably, the bottom of the quartz strip is provided with an adsorption hole, the fixing base is provided with a vacuum hole communicating with the adsorption hole, and the vacuum hole is connected to a vacuum suction tube.

[0009] Preferably, there are multiple vacuum holes, which are spaced apart on one side of the fixing base in the width direction.

[0010] Preferably, one side of the fixing base in the width direction is provided with a plurality of fixing screw holes at intervals.

[0017] One of the above technical solutions has the following beneficial effects.

[0018] This invention optimizes the structure of the pre-pressure head by adding an LED light inside, which illuminates the quartz strip below the LED light.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0033] Implementation Method 1

[0034] Misalignment can easily occur when bonding FPC boards and displays, affecting bonding accuracy.

[0035] The luminous pre-pressure head of this invention includes a fixed base 1 with a mounting groove at its bottom; an LED light 2 disposed within the mounting groove; and a quartz strip 3 embedded in the mounting groove. The bottom of the quartz strip 3 has a protrusion 31, which at least partially protrudes from the plane of the bottom of the fixed base 1. This invention optimizes the structure of the pre-pressure head by adding an LED light 2 inside, causing the quartz strip 3 below the LED light 2 to emit light. This improves the reflection problem of the CCD lens, aids in CCD lens positioning, and thus increases work efficiency. Simultaneously, the light from the LED light 2 covers the imaging area of ​​the CCD lens, improving the clarity of the CCD lens and helping to solve the problem of deviation during FPC board and display screen bonding, thereby improving bonding accuracy.

[0036] The quartz strip 3 has a protrusion 31 at its bottom that extends beyond the bottom plane of the mounting base 1, facilitating contact with the FPC board through the protrusion 31. The LED light 2 emits light through the quartz strip 3. When aligning the auxiliary CCD lens, the addition of a light source in the pre-pressure head improves the clarity of the CCD lens, thereby solving the problem of misalignment during the bonding of the FPC board and the display screen and improving bonding accuracy. The LED light 2 is preferably red, but other colors are also possible and are not limited here.

[0037] In the luminescent pre-pressure head according to this utility model, the bottom of the quartz strip 3 is provided with an adsorption hole, and the fixing base 1 is provided with a vacuum hole 4 communicating with the adsorption hole. The vacuum hole 4 is connected to a vacuum suction tube. Specifically, the quartz strip 3 forms the adsorption hole by drilling, and the adsorption hole is connected to the vacuum suction tube through the vacuum hole 4, so that the protrusion 31 of the quartz strip 3 can adsorb the FPC board, that is, during the binding process, it adsorbs the FPC board to be bound. Among them, there are multiple vacuum holes 4, specifically, five vacuum holes 4 are arranged at intervals, which helps to improve the adsorption effect of the quartz strip 3 on the FPC board, so that the FPC board is evenly stressed at all positions. The multiple vacuum holes 4 are arranged at intervals on one side of the fixing base 1 in the width direction, which facilitates the connection of the vacuum suction tube to the vacuum hole 4 and helps to improve the installation efficiency. In addition, one end of the vacuum suction tube is connected to the vacuum hole 4, and the other end is connected to a vacuum pump, so that the quartz strip 3 can adsorb the FPC board.

[0038] In the luminous preload head according to this utility model, a plurality of fixing screw holes 5 are provided at intervals on one side of the fixing base 1 in the width direction. Specifically, the fixing screw holes 5 are arranged at intervals, and there are 5 of them. The quartz strip 3 is fixed in the preset position by screws to prevent the quartz strip 3 from shifting or shaking. At the same time, it is convenient to disassemble and install the quartz strip 3, so that the quartz strip 3 can be replaced according to actual production needs to match different sizes of FPC boards, which helps to improve the compatibility of the preload head.

[0039] In the luminous pre-pressure head according to this utility model, a mounting hole is provided on one side of the fixing base 1 along its length, and a heating tube 6 is disposed in the mounting hole. Specifically, the heating tube 6 is located above the mounting groove.

[0040] The working principle of this utility model is as follows:

[0041] This invention optimizes the structure of the pre-pressure head by adding an LED light 2 inside the pre-pressure head, which causes the quartz bar 3 below the LED light 2 to emit light. This improves the reflection problem of the CCD lens, helps with the positioning of the CCD lens, and thus improves work efficiency. At the same time, the light from the LED light 2 covers the shooting area of ​​the CCD lens, which can improve the clarity of the CCD lens and help solve the problem of deviation when bonding the FPC board and the display screen, thereby improving the bonding accuracy.

[0042] Implementation Method 2

[0043] Unlike embodiment one, the mounting groove in this embodiment has a bottom and a wall. The wall forms a downward opening. When installing the quartz strip 3, the bottom of the quartz strip 3 faces downward, and the protrusion 31 of the quartz strip 3 also faces downward, which facilitates the contact between the protrusion 31 of the quartz strip 3 and the FPC board. The bottom of the groove has a recess, and the LED light 2 is fixed in the recess, so that the LED light 2 can be embedded in the recess, avoiding displacement or shaking of the LED light 2. In addition, both the mounting groove and the quartz strip 3 extend along the length of the fixing base 1. Specifically, the mounting groove is a through groove, which facilitates the installation of the quartz strip 3 in the mounting groove.

[0044] The other structures are the same as in Implementation Method 1, and will not be described again here.

[0045] Implementation Method 3

[0046] Unlike Embodiment 1, the protrusion 31 in this embodiment has a square cross-section, which helps to increase the contact area between the protrusion 31 and the FPC board. The protrusion 31 and the bottom of the quartz strip 3 have an arc-shaped transition to prevent the edges of the quartz strip 3 from scratching the FPC board. The mounting base 1 has a T-shaped cross-section, which facilitates the installation of the mounting base 1 on the pre-compression device.

[0047] The other structures are the same as in Implementation Method 1, and will not be described again here.
